IMPROVEMENT IN EOISTING-IVIACHINE.

TO ALL WHOM IT MAY C'ONCERN: v

Be it-known that I, GEORGE R. CLARKE, ofl the city, county, and State of New York, have ivented'a new. and improved Hoisting-Machine, which isv clearly and fully described as follows: l

Figure 1, of the accompanying drawings, is a side view of a vertical section `through the centre.

Figure 2 is an end view with the end casing removed.,

Figure 3 is an end view with the casing. I Y

Like letters and numerals 'refer to likepartsin eachiigure.

represents the frame4 B represents the roller; C, the casing inA which the gearings are enclos'ed; D is A the crank; E and F are dogs, (seeg.2,) byjvhich gear-wheels 32 and 33 are clutched, when desired.'

16 Vand 15 are piniou-wheels,.which mesh into 32 and 33, These numerals indicate the number .of cogs in each' wheel. i v I J G'r is a clutch, operated by screw vS,`by which 16 and 15 .aremade fast together, when desired.

l H is a shipper-apparatus, shaped as shownin Figure 4,.the end of which is seenin g..2, by which dogs E and F are made to clutch wheels 32 and 33,'whendesired.` I

When levenL, which is attached to H,is made t-point to` I, (see iig. 3,) 32 clutched, when L points tol J, y33 is clutched, when L points to K, neither one is clutched. M, (lig.` 3,) is a projection ofthe case C, and is a kind of hub, in which there is a niche, into`which a dove-taillike fulcrum, mfrts, which projects from the inner side at the inner `end of the crankA D.

v Fig. 3 shows two slots in the crank lengthwise, also a. circular'opening, in which the shaft ofthe p inions I6 and 15 may revolve, when desired. These slots enablethe' crank to be shipped when it is desired to connector disconnect the crank with M. Y I

The inner slot also admits the tenon t, which-isvon the end of the shaft of pinions 16 and 15, to enter, and thus prevents the revolution of the shaft on its own axis, when it is so desired'. l

Immediately behind crank D is .an irregular-shaped collar, Figure 5,) which' is permanently attached to a hub--likc projection of C'in such a. manner.` asto befree to revolve upon this huh-like projection, when'desired.

In one end of collar O is a niche, the same as in m, to receive the fulcrum n., while the otherend of O receives the s'erewP, (see iig. 1,) hy which the crank D is held in proper relation, to O,

Now then, wheel 32 being fast to frame-A by screw I, it is at all times immovable, and 33 being fast to roller B by screw 2, 33 and B must always'move together as one.

When 33 is clutched `by dog E, and crank is connected with m by fulcrum n, then the cranlrd, casing C, and roller B all revolve together, beinga. simple' crank-and-windlass motion.'

vWhen 33 is not clutched, and 32 is clutched, and pinion 16 is free, and the shaft of pinion 15 is embraced byfthe slotin crank D, and fulcrum mis freed from '12, then the revolution of D is two to one of B.

But when 32 and 33 are not clutched, and 16,andr15 are clutched by G and-freed from D, and Dis clutched to m, then the' crank, D, and case C revolve together, making eleven revolutions to one of D.

Again, if crank D is freed from m,'and made to revolvefl and 15 are free to revolve together around wheels 32 and 33, p inion 16 will have made4 two complete revolutions around.l 32, pinion 15.(heing clutched to i 16) will have made the same revolutions and have travelled the sume distance, but willhave lacked three cogs f of having travelledonce around 33. A

Hence, when I6 has made two complete revolutions, and carried 15 withjit, to the vsame point of starting, it followsihat 33, with B, has advanced threecogs, in order to permit I5 to arrive at the p oint of starting in company with 16;

Thus, in this'cascwandV arrangement, we nd that roller B, with Wheel 33, has advanced three thirty-thirds of one revolutionduring one revolution .of the case C, and twov revolutions of pinions 16 and 15, and for three revolutions of crank D. Hence it' requires, with this last-described arrangement, eleven'rcvolutionsof the' case G, twenty-two revolutions o pinons 16 and 15,-'and thirty-threerevolutions of crank D- to make one revo iution of roller B.

Y Crank is compelled to maketliirty-three revolutions in consequence of `16j and v15 having made twentytwo revolutions eeoh, on their own axle-and eleven revolutions aroimd' theaxes of their priniaries 32 and 3.3.

It is not essential that pinions 16 and. 15 should have a diverse numberv ofu' eogs,' `nor. `is it essentiel that wheels 32 and 3 3 should have a, like diversity offeegs, es herein described. I

The same mode of obtaining` power and motion, as herein set lfortl1, 'is eminentlya'dapted lto steering ves-y sels, to capstans, and to alljp'resses reqiring great power, such alsvlay a'nd cottonflpresses'.

What I claim Letters Patent for-lof' the United Stzttes, is A Primerym'heels '32 and 33, pinion-Wheels 16 and 15, in'eom'nmitionv withv revolving ca'se C.

. Also, revolving'cese' 0, crank D, and collar O, when constrnctell, arranged, Iand-operated substantially as herein set forth. v.

GEOffR. CLARKE.
